is usual in type slug casting machines, to make up the complete table or form of 3 is a brass rule adapted to be disposed vertically with respect to the column of sings and the function of which is to provide means for printing a vertical ruling line such as may be employed toseparate columns of figures, for instance.

drawings a "of these rules are .shownin connection With the column of slugs but only one may be employed or a greater number than those shown may be used if desired. The preferable form of this rule is indicated inFig. 3, and in cross usual height of the type and quad the heightof the rule willbe preferably 5/32 of an nch The rule is preferably 1/16 of an inch wide at its bottomsna1/s2 of an inch at the lower edge a of the level of the top of the quad.

Aslot l is sawed ln such slug and the upper -edges; of the slot is quad high.

The slot extends downwardly from the. surface of the quad, preferably for a depth of 5 /32 inches and is narrower at the top than at the bottom and ispreferably. clove-tailed in shape, being approximately 1/16 inch Wide at the bottom and 1/32 inch Wide at the.- topof the slot. The quad surface. is formed by that portion of the upper edge of the slug-from which the base on'which the printing character is cast, projects. .,In

producing these slots, a series of the slugs 'is arranged in: Vertical ,column to form 'the complete table or form and then a continuous line of dove-tailed slots is sawed directly in the quad surfaces of the slugs. The table ,dr formis then removed to the press for printing therefromh By this method the dove-tailed slots are formed and retained in perfect alinement and castings of the slugs to provide the rule-holding means by the use'of special matricesisavoided- After the line of slots has been'sawed, the rule is placed therein by inserting the rule into the slots at the endof the line and it is firmly held in the 'slbtsifagainst escape in a vline perpendicular to the face of the type,

Without further manipulation of the slugs or rule.

In addition to the advantages of obtaining alinement and dispensing with the use of special matrices, our invention also possesses quad surface.

slots dispenses with the use of extra leads. with slots or braces therein.

the following advantages. It is impossible for the rule to pull out of a form in printing. Less than half the time consumed by other methods now in use is required in theuse of our invention to insert or remove the rules. The rule may be cutin labor saving lengths and can be used many times, thus eliminating the cost of a new rule for different jobs and the rule may be used on any size of slug, leaded or solid, with type faces ranging from 45- to 48 point. The continuous slot may be sawed for as great a length I as 5" with one movement, thus saving time. Thls lnvention also saves time in enablmg revise corrections to made readily as the rule can be removed and replaced,

easily.

The particular advantages of the process employed, in addition to that already referred to are-that as compared with casting special rule holding bodies or sawing or punching openings, the edges of which must be bent to secure the rule, it does not require two operations, nor a specially built machine for casting the slugs. The slots are below quad high surface as compared with the present objectionable process of having the rule holding means projecting above the Our methodof sawing the Having thus described our invention what we claim is:

1. A printing form having a plurality of slugs bearing printing characters arranged with their adjacent faces in contact, said form having a continuous line of'rule locking recesses formed in the bodies of the individual printing character slugs and between the ends of the respective slugs and below the quad surfaces thereof, whereby the ruleis locked to each slug through which it passes, in combination with a rule extending at right angles to the lengths of the slugs and formed to-engage "said recesses, substantially as described. v

2. A printing form having a plurality of printing character slugs disposed face to face,- said form having a continuous line of, slots for holding the rule, each of said slots being formed in the body of and between the ends of a printing characterslug, said slots extending downwardly from the quad surfaces and below the same, and being narrower at their upper ends than at the lower ends, in combination with a rule extending at right angles to the lengths of the slugs and formed complementarily to the slots and engaging the latter, substantially as described.

3. In combination with a printing form, a rule adapted to extend at right angles to the lengths of the slugs'composing the form, in combination with a printing character bearing slug in said form, provided with a rule locking recess in the body of the slug between the ends thereof, and extending downwardly from the quad .surface of the slug, said recess being formed to retain the rule against withdrawal in a line perpendicular to the printing face, but permitting the insertion of the rule through the side-of the slug, substantially as described.

4. A printing form having a plurality of slugs bearing printing characters, said slugs being provided with dove-tailed slots formed in the bodies of the slugs and extending from and below the quad surfaces
